St John's Church is on the skyline when you exit Queen's arcade. It is the oldest building in the city centre with records going back to 1180. It was rebuilt in the 15th century.Style is late perpendicular.It has a tower 130 ft high.Inside is the Hubert Chapel, named after the Hubert brothers who were private secretary to Queen Elizabeth I and James I, and the other Keeeper of Cardiff Castle. Therenis also Victorian stained glass window, and the Chapel of the Order of Saint John, with memorials to Lord Kitchener and King Edward the VIII, who abdicated before he was crowned.It has a tea room that has been open every time I have gone past.The churchyard has a number of interesting stones and a pillar somewhat resembling a market cross. In November before Remembrance Sunday bouquets of flowers were lying on the small plinth, and nearby were the insignia of many army regiments.As a genealogist I was horrified to find the pathway to the church was made from slabs from the graves of people, many early graves from the 18th century. Some of the information is still legible, but for how long?
